The Cheapest Way to Send a Parcel (verdict by size and weight)
If you’re looking for the cheapest way to send a parcel in Australia, the answer depends on the size, weight, and destination of your package. Delivery zones across Australia can affect rates, and parcel delivery costs can vary by 30-50% depending on destination.
Whether you're sending a letter, a heavy parcel or something in between, at Zappy our goal is to take the guesswork out of your shipping needs.
Cheapest Shipping In Australia by Parcel Type
Under 500g
For packages under 500g, Australia Post’s Prepaid Satchels are typically the cheapest and most convenient option. They’re easy to buy, offer flat-rate pricing, and can be dropped off at any post box or post office. For metropolitan deliveries, some same-day courier services can be competitive, but Australia Post is usually the cheapest postage Australia-wide.
1–5kg
In this weight range, courier services start to offer real competition. Aggregators like Zappy, Transdirect, and Interparcel can often return a courier quote quickly and undercut Australia Post, especially for city-to-city routes. They also simplify shipment management with a single dashboard for tracking.
5–22kg
For 5–22 kg parcels in Australia, you can find the cheapest options by comparing rates through aggregators which discount commercial carriers like Australia Post, CouriersPlease, and Aramex. Direct retail pricing for heavier parcels shifts quickly depending on cubic weight and distance. For example, booking with Zappy gives you access to different courier rates so you can find the right price for what you need.
Large and Bulky Items
Shipping furniture or other bulky items? Large packages need careful packing, because oversized boxes can lead to expensive shipping by making you pay for empty space. Snug packaging can reduce shipping costs significantly by limiting cubic-weight charges. Specialist courier services or freight brokers are generally your best bet, as Australia Post can’t handle oversize parcels. Zappy can help you compare options and book directly with transport companies. For suitable non-fragile items, poly mailer satchels are lightweight alternatives to boxes, though bulky goods still usually need specialist carriers.
Australia Post vs Courier Services — When Each Is Cheaper
Australia Post is often the right service for small, lightweight items, PO Boxes, and some remote deliveries because it is generally more reliable for tracking and final delivery than some private couriers. Comparing alternatives can help you find better prices for heavier parcels or bulk shipments, while also weighing the chance your parcel is delivered smoothly. Keep in mind that some destinations may only be accessible through Australia Post.
How a Shipping Aggregator Gets You Below Retail Rates
Shipping aggregators combine the shipping needs of many customers to get discounted rates from trusted carriers that aren’t available to individuals. Using their services can make you feel resourceful and in control of your shipping costs, especially if you ship regularly.
Take Zappy, for example: you simply book online to compare courier quotes in one place instead of checking multiple courier websites. Then you can choose the best deal and print your shipping label at home. Transparent quotes help you avoid hidden fees and nasty surprises before you pay.
Pre-Negotiated Volume Rates Explained
Couriers give their best discounts to large businesses that ship a lot. Aggregators use the combined shipping volume of all their users to get similar discounts for everyone, so even people who ship only occasionally can benefit from lower prices.
Cheapest Interstate Routes Compared
Sydney to Melbourne
This is Australia’s busiest parcel route, and competition keeps prices low. Aggregators and couriers almost always beat Australia Post on price for anything above 500g—sometimes by as much as 30%. Even on major capital cities routes, parcel delivery pricing can still vary by 30–50% based on the exact pickup and drop-off suburbs.
Shipping to Perth
Shipping to Western Australia is more expensive regardless of the provider. Couriers through aggregators can help you find the best price, but shipping farther west or into remote parts of WA can increase costs by 30–50% even when the base courier price looks cheaper, so always check for surcharges and delivery times since faster services on this route often come with premium rates.
Regional and Residential Surcharges and Hidden Fees
Australia Post and other couriers can add surcharges for remote or residential delivery services. Some remote destinations are subject to extra fees beyond the headline rate. Being aware of these surcharges can help you feel prepared and avoid surprises, so check the full quote in advance for a timely manner of delivery and a cleaner cost comparison before you book.
How to Cut Shipping Costs If You Ship Every Week
If you send parcels regularly, Zappy can help you. As an aggregator, we can help you compare couriers to get the best rates available, and frequent business senders may also get discounted rates by opening carrier business accounts. If your weekly volume is high enough, that can be the most affordable way to lower regular postage costs. You can also use prepaid satchels for standard-sized items, and remember to compare prices before you send anything so you save on price without giving up consistent service.
FAQs
What Is the Cheapest Way to Send a 5kg Parcel?
Use a courier service via a shipping aggregator for the lowest rate. Australia Post’s Parcel Post rates are rarely the cheapest above 5kg, while a courier via an aggregator usually wins. Large packages are also more likely to be priced on size as well as weight, which is why courier comparison matters here.
What Is the Cheapest Courier for Small Business?
Small businesses often use platforms that let them compare prices across delivery services to find a cheaper price and book online quickly. Aggregators are a fantastic way to access discounted booking tools without negotiating directly with each carrier.
Is Australia Post or a Courier Cheaper?
For small, light parcels, AusPost is often the cheapest courier Australians rely on. For heavier or bulky items, couriers via aggregators are usually better value for bulky domestic jobs and many international shipping needs while still being a practical option in Australia. If you also send international parcels, you may need customs forms and customs documents during booking, so contact the relevant customs authority or carrier if you're unsure about prohibited items or charges.
Stop Paying Retail Shipping Rates
To find the cheapest way to send a parcel in Australia, compare prices first and choose the service that fits the size, destination, and delivery speed you need. Avoid paying full price at the post office counter. Small packages going within the same city can be priced differently from interstate deliveries, so the cheapest option is not always the same.
Zappy can help you find courier discounts and make sure you’re not caught off guard by extra charges or unaware of special offers based on your parcel’s size, weight, and where it’s going. It also helps you compare rates across courier services so parcels reach customers safely without overpaying.
